Easy Walk uses a mobile phone that runs the Symbian operating system, a small Bluetooth GPS receiver,text to speech software called Talks (though rival products are also compatible) and a call centre that will operate around the clock seven days a week.

It requires just two dedicated keys on the mobile phone - one which, when pressed, tells the user their exact location including the house or building number and the other one alerts the call centre that the person needs assistance with navigation.

An operator will then call the blind person, find out where it is they need to go and stay on the line with them providing step by step instructions.

Easy Walk is the brainchild of Andrea de Paoli, Il Village’s technology officer.

This is a concept that Mr de Paoli refers to as having a “guardian angel” who makes sure that anyone using the system gets to where they need to go

Because Easy Walk uses digital maps, in theory the call centre staff would be able to provide guidance to a user anywhere in Europe.

The system has already been tested across the border in France and Switzerland.

While that may be great for “America’s Funniest Home Videos,” it doesn’t allow you to find help—or your way home. Brickhouse Security takes the car-cam one step further with GPS features in the Car Camera Voyager Pro.

Engadget says that the unit includes a G-sensor. That means your car knows when it’s been messed with, triggering the camera to record 10 seconds before and 30 seconds after any incident. How it knows to start recording makes it sort of supernatural, but we’re willing to take their word for it.

The GPS can also document where the incident happened, on the off chance that you drive around for days without noticing your bumper half hanging off.

The 2008 Suzuki SX4 is the first vehicle of any sort to be priced below $16,000 and have a standard navigation system.

Suzuki created a flip-up position at the top of the dash to hold the Bluetooth GPS system. It clicks right in and charges while connected to the dash as opposed to the suction cup and wires down to the cigarette lighter outlet. The system connects through the stereo so it will automatically lower the radio’s volume before directions.

The little compact car, which goes against the likes of the Mazda 3, Ford Focus, Toyota Corolla, and Honda Civic, may come across as more cheap and cheerful than bold and beautiful, but for the money it’s a good deal.

 GPS global positioning system is the core of the future functioning of the force, its military technology from the United States evolved from the phone, transportation, aviation, surveying and mapping and first aid in areas such as extensive application.  In the car with the GPS anti-theft vehicles will be able to automatically download the current location, speed and other information, and this information will be timely feedback to the owner.In the aviation field, GPS is able to greatly enhance the accuracy of the flight, such as bad weather like fog this application is very important.

GPS systems built in 1978, in heaven operation of the 29 sent to the satellite positioning signal, the ground receiving equipment on these signals to achieve the targeted latitude and longitude. GPS is with us ever closer integration of life, may even be completely changed our way of life.

 In the next few years, Russia’s GLONASS and the European GALILEO will provide a more accurate and cheaper location-based services, will break the monopoly of GPS for many years. Based on the navigation services once universal, personal life will cause great change.

 Corresponds to the actual application, the location of three known, is not responsible for the three satellites, because the satellite is in accordance with the “ephemeris” precision operation, so it at a certain time we can know the location, which meet the mathematical principle , The first problem solving; second condition is that you need to know that the relative distance from three satellites, satellite launch a specific radio signal, the GPS receiver you receive this signal is later than the time difference, because the radio Transmission speed is known, through this time difference is you can calculate the distance between the satellites. Two conditions are met, you will come out of position.

These are only the GPS principle of a simple description, but also practical applications much more complex, in fact reached 3 D positioning, at least four satellites, to more than one is used to award the.  Interested friends can access the relevant information to satisfy your curiosity.

 Understand the principles of GPS positioning, we will find out that, although the mathematical principle is very simple, but through physical means to achieve the two known conditions, is a very complicated matter.

First, the satellite in the sky to fly, who can not guarantee that it can not slightest difference in their tracks, there are always more or less the deviation.  Second, the GPS receiver, you can not on a cesium atomic clock, the transmission speed of radio waves per second is about 300,000 km, a simple calculation you can see, if the error 0.00001 second time, the number of poor distance?  Even if you do not have the time error, the radio waves will spread in the air by many factors, such as weather. The impact of the above is not the most important, more important reason is that the impact of how much you can receive satellite signals.  GPS signals are very weak, then receiver on a small ceramic antenna, you can also count on what is good effect?  So basically what they are irresistible, you will not received signals, even if you have received a 10 eight strong satellite signal, we will certainly be very accurate? No. If you just catch up with this Zhacheng 10 satellites are a bunch of meetings, or a neat line of home school team, then you will have some trouble

As in the upcoming low-end CDMA handsets, Nokia’s market position and not because of the phone and in the design of some of the slightest ambiguity. Although the overall shape of the aircraft did not launch in April this year, the Nokia 6600 (comments) f people as impressive, but the details of handling this by folding design of the three series of phone or a fashion show phone features, such as the introduction also The mirror of the popular design and hidden Waibing design, and polishing the mirror in the phone casing, in addition to design a special feeling for the dedicated multimedia keys, also has a 1.2 inches resolution of 128 × 128 pixels The 65 K TFT color screen, can display such as time, date, day-to-day calls, and other information, can also play music in the show repertoire of songs and relevant information. However, because of market-based positioning, the Nokia 3608 the main screen using a 2.0-inch resolution of 176 × 220 pixel 260,000 color TFT screen and use the S40 platform and operating system interface. It is worth mentioning that, Nokia also for the aircraft also provided a GPS navigation capabilities that can easily use the support network of various services related to mobile navigation.

The Nokia 3608 is also equipped with a 1.3-megapixel camera, 4x digital zoom and video capture function, compatible MP4, AAC & eAAC +, WMA audio format and 3 GPP H.263, H.264 and video file formats, such as MPG4 Player, built-in FM radio, cell phone in the fuselage with 15 MB of memory, but also through micro-SD memory card extended to 4 GB capacity. As for the main functions of the phone, the Nokia 3608 also supports the CDMA 800/1900MHz networks, and supports Bluetooth and USB2.0 connection, equipped with a 2.5 mm headset interface, the fuselage book can store up to 1,000 contacts, support SIND (Non-specific language to name dial-up), equipped with mobile phones in the BL-4B battery case, will be up to 11 days of standby time and continuous 3.5 hours of talk time.。 It is worth mentioning that, although the plane has been the official website there, but it was not clear when the aircraft will be officially published. At the same time RUIM support aircraft based on the details, The Nokia 3608 mainly targeted at China and the Asia-Pacific markets more likely.

Some developers said that they are doing so because the iPhone is the application of the distribution model. ITunes users through their own,accounts rather than iPhone cell phone to get an application.  For example, three mobile phones with an iPhone iTunes accounts simultaneously, so that only pay a fee, but if directly on the machine, you need to pay two-thirds the cost.

 In addition, the developer of iTunes also dissatisfied with the billing system. iTunes iTunes is usually to a monthly subscription package or on the way to map the costs of services received, and most of the developers are billing the flow. 。 But Apple’s short term does not seem to adopt this model. Developers said that the company only offers two pricing model: either free or a monthly subscription (9.99 U.S. dollars) or packet (2.99 U.S. dollars). Developers and even suspected that Apple has developed its own navigation procedures, even if the iPhone is very popular, they still remain cautious.

Dutch TomTom company is also testing the iPhone on its navigation software.  The company’s contract to Tele Atlas and Google has just signed a five-year agreement. And Google map precisely iPhone is the default map services.However, TomTom does not intend to launch the iPhone on commercial software.The company spokesman said that they will further observation Apple’s strategy, before we know whether there is opportunity.

   Even the application of smaller companies also have questioned the Apple iPhone. New York-based company Citysense development of the application process is designed to track people’s nightlife, the application needs to open a long time to play a role.  However, in order to conserve battery, iPhone to allow only one run an application, thus greatly limiting the use of the software. In order to solve this “single mission” mode, the company in June announced a tool in the mobile phone users from “sleep” mode when the wake-up automatically updated geographic information. But not all the positioning of the iPhone procedures are in support of this model. Developers continue to update location information that way more attractive.

Things are much, much easier today. For less than $100, you can get a pocket-sized gadget that will tell you exactly where you are on Earth at any moment. As long as you have a GPS receiver and a clear view of the sky, you’ll never be lost again.

In this article, we’ll find out how these handy guides pull off this amazing trick. As we’ll see, the Global Positioning System is vast, expensive and involves a lot of technical ingenuity, but the fundamental concepts at work are quite simple and intuitive.

When people talk about “a GPS,” they usually mean a GPS receiver. The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). The U.S. military developed and implemented this satellite network as a military navigation system, but soon opened it up to everybody else.

Each of these 3,000- to 4,000-pound solar-powered satellites circles the globe at about 12,000 miles (19,300 km), making two complete rotations every day. The orbits are arranged so that at any time, anywhere on Earth, there are at least four satellites “visible” in the sky.

A GPS receiver’s job is to locate four or more of these satellites, figure out the distance to each, and use this information to deduce its own location. This operation is based on a simple mathematical principle called trilateration. Trilateration in three-dimensional space can be a little tricky, so we’ll start with an explanation of simple two-dimensional trilateration.
